Now, the user specifically mentions a release by "Mrmovi". But Mrmovi isn't a company I'm immediately familiar with. Maybe it's a typo or a less-known entity. I'll need to check if this is a legitimate release. Typically, official Blu-rays for movies like "Oblivion" are released by major studios, such as 20th Century Fox or later Disney (since Fox was acquired by Disney). However, the user might be referring to a regional or pirated release, which can sometimes have different labels. It's possible that "Mrmovi" is associated with a pirate market or a less-known legitimate distributor, but I need to be cautious here to avoid providing information about pirate content.

So, "Oblivion 2013" is likely the movie released in 2013 titled "Oblivion", directed by Joseph Kosinski and starring Tom Cruise. The user is interested in a specific release of this movie on Blu-ray, possibly by a group or publisher called "Mrmovi". The title mentions "hybrid open matte BD", which suggests that the release might have both an open matte and a standard aspect ratio to preserve the original cinematography.

I also need to note that if this is indeed a pirated release, sharing or linking to it is against the law and violates copyright. The user should be encouraged to seek out official versions through legitimate retailers or streaming services. Additionally, I'll explain what the hybrid open matte means in terms of the viewing experience, maybe how the aspect ratio affects the image and why some people prefer one over another.
